Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

fat: convert to unlocked_ioctl FAT does not require the BKL in its ioctl function, which is already serialized through a mutex.

[PATCH] add -o flush for fat Fat is commonly used on removable media. Mounting with -o flush tells the FS to write things to disk as quickly as possible. It is like -o sync, but much faster (and not as safe).

writeback: separate out include/linux/backing-dev-defs.h With the planned cgroup writeback support, backing-dev related declarations will be more widely used across block and cgroup; unfortunately, including backing-dev.h from include/linux/blkdev.h makes cyclic include dependency quite likely. This patch separates out backing-dev-defs.h which only has the essential definitions and updates blkdev.h to include it. c files which need access to more backing-dev details now include backing-dev.h directly. This takes backing-dev.h off the common include dependency chain making it a lot easier to use it across block and cgroup. v2: fs/fat build failure fixed.

[patch 3/4] fat: dont call notify_change The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change the file mode before changing the inode attributes. Replace with explicit calls to security_inode_setattr(), fat_setattr() and fsnotify_change(). This is equivalent to the original. The reason it is needed, is that later in the series we move the immutable check into notify_change(). That would break the FAT_IOCTL_SET_ATTRIBUTES ioctl, as it needs to perform the mode change regardless of the immutability of the file. [Fix error if fat is built as a module.

fatfs: add FAT_IOCTL_GET_VOLUME_ID This patch, originally from Android kernel, adds vfat ioctl command FAT_IOCTL_GET_VOLUME_ID, with this command we can get the vfat volume ID using following code: ioctl(fd, FAT_IOCTL_GET_VOLUME_ID, &volume_ID) This patch is a modified version of the patch by Mike Lockwood, with changes from Dmitry Pervushin, who noticed the original patch makes some volume IDs abiguous with error returns: for example, if volume id is 0xFFFFFDAD, that matches -ENOIOCTLCMD, we get "FFFFFFFF" from the user space. So add a parameter to ioctl to get the correct volume ID. Android uses vfat volume ID to identify different sd card, when a new sd card is inserted to device, android can scan the media on it and pop up new contents.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

[PATCH] fat: support a truncate() for expanding size (generic_cont_expand) This patch changes generic_cont_expand(), in order to share the code with fatfs. - Use vmtruncate() if ->prepare_write() returns a error. Even if ->prepare_write() returns an error, it may already have added some blocks. So, this truncates blocks outside of ->i_size by vmtruncate(). - Add generic_cont_expand_simple(). The generic_cont_expand_simple() assumes that ->prepare_write() can handle the block boundary. With this, we don't need to care the extra byte. And for expanding a file size by truncate(), fatfs uses the added generic_cont_expand_simple().

fat: Opencode sync_page_range_nolock() fat_cont_expand() is the only user of sync_page_range_nolock(). It's also the only user of generic_osync_inode() which does not have a file open. So opencode needed actions for FAT so that we can convert generic_osync_inode() to a standard syncing path. Update a comment about generic_osync_inode().

fat: Cleanup FAT attribute stuff This adds three helpers: fat_make_attrs() - makes FAT attributes from inode. fat_make_mode() - makes mode_t from FAT attributes. fat_save_attrs() - saves FAT attributes to inode. Then this replaces: MSDOS_MKMODE() by fat_make_mode(), fat_attr() by fat_make_attrs(), ->i_attrs = attr & ATTR_UNUSED by fat_save_attrs(). And for root inode, those is used with ATTR_DIR instead of bogus ATTR_NONE.

fat: Fix ATTR_RO for directory FAT has the ATTR_RO (read-only) attribute. But on Windows, the ATTR_RO of the directory will be just ignored actually, and is used by only applications as flag. E.g. it's setted for the customized folder by Explorer. http://msdn2.microsoft.com/en-us/library/aa969337.aspx This adds "rodir" option. If user specified it, ATTR_RO is used as read-only flag even if it's the directory. Otherwise, inode->i_mode is not used to hold ATTR_RO (i.e. fat_mode_can_save_ro() returns 0).

fat: fix data past EOF resulting from fsx testsuite When running FSX with direct I/O mode, fsx resulted in DATA past EOF issues. fsx ./file2 -Z -r 4096 -w 4096 ... .. truncating to largest ever: 0x907c fallocating to largest ever: 0x11137 truncating to largest ever: 0x2c6fe truncating to largest ever: 0x2cfdf fallocating to largest ever: 0x40000 Mapped Read: non-zero data past EOF (0x18628) page offset 0x629 is 0x2a4e ... .. The reason being, it is doing a truncate down, but the zeroing does not happen on the last block boundary when offset is not aligned. Even though it calls truncate_setsize()->truncate_inode_pages()-> truncate_inode_pages_range() and considers the partial zeroout but it retrieves the page using find_lock_page() - which only looks the page in the cache. So, zeroing out does not happen in case of direct IO. Make a truncate page based around block_truncate_page for FAT filesystem and invoke that helper to zerout in case the offset is not aligned with the blocksize.

check ATTR_SIZE contraints in inode_change_ok Make sure we check the truncate constraints early on in ->setattr by adding those checks to inode_change_ok. Also clean up and document inode_change_ok to make this obvious. As a fallout we don't have to call inode_newsize_ok from simple_setsize and simplify it down to a truncate_setsize which doesn't return an error. This simplifies a lot of setattr implementations and means we use truncate_setsize almost everywhere. Get rid of fat_setsize now that it's trivial and mark ext2_setsize static to make the calling convention obvious. Keep the inode_newsize_ok in vmtruncate for now as all callers need an audit for its removal anyway. Note: setattr code in ecryptfs doesn't call inode_change_ok at all and needs a deeper audit, but that is left for later.
